 - [x] Add unit and installer regression tests and coverage threshold.

   idempotent CLI install/uninstall and native agent discovery.

+  unrelated plugins, and a user-owned skill; verify repeat install and
+  conservative uninstall after a managed-file edit.

   and execution in OpenCode 2.0.24 against a local mock provider.
